Is there a way to add a Javascript-based Signature Pad to a Google Form to capture a responder's signature?

Is there a way to add a Javascript-based Signature Pad to a Google Form to
capture a responder's signature?

Is there a way to add in Thomas Bradley's Signature Pad plugin so that
someone who is filling out the Google Form would be able to sign the form?
Would it be possible to use the HTML Service option to create a custom
HTML form web app that can then still upload the responses into a Google
Spreadsheet?
The project I've been asked to look into involves an individual being able
to fill out a form but they would also like to be able to capture a
signature (essentially a web form replacing paper forms) and they would
like to do it all with Google since it is their preferred service. They
also prefer to use Google Spreadsheets.
I'm very new to Google App Scripts and have a beginner's understanding of
Javascript so I may very well misunderstand the uses and potential of
Google App Scripts. Any help or advice is much appreciated.
